I'm using the System.Drawing.Bitmap class for loading a 32-bit bmp file which
includes an alpha channel.
The problem is, when it gets loaded (just using the Bitmap(string filename)
constructor), it doesn't bother bringing the alpha along with it. All of the
pixels just show "255" as their alpha value and Bitmap.IsAlphaPixelFormat()
returns false.
I know that the alpha does exist physically and has worked with this exact
image in other...

hello,
- I have a Bitmap Object named: bmp1
- I already have the numerical values of:red,blue and green colors + I have
the X and Y cordinates.
How do I set the pixel value via safe code on the bmp1 object?
(the pixel location based on the X & Y values and it's color based on the
red,blue and green values the I already have)

I know that one technique would be to do the following:

Dim arrayLength As Integer = (bitmapData.Stride * bitmapData.Height)

In a previous post I have been asking about a way to test Alpha
Transparency.
Bob and Michael have kindly provided some ideas.
Here I would like to share the function I have prepared, for the
purpose to improve it.
Frankly, I am not clear about the exact meaning of some pixel format
(max, gdi, etc.) and I hope I have put them under the right "case". I
have made only some superficial test and it seems to work.
Note that the purpose is...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
